Type definition for cleanup() is missing

[ahaverty]

firebase-functions-test: v0.1.1

firebase-functions: v1.0.1

firebase-admin: v5.12.0

Test case

import 'firebase-functions';

import * as admin from 'firebase-admin';
import * as firebaseFunctionsTest from 'firebase-functions-test';

firebaseFunctionsTest.cleanup(); //=> Property 'cleanup' does not exist on type...

Expected behavior

Type definition for cleanup() of firebase functions test in typescript.
